from an aperture 7 in the front 3 of the camera.

' The shutter member 5 is rigidly secured on a shaft 8, appropriatelyjourn'aled 'on a wall 9 extending transversely across the casing or box2, and in which wall is formed an aperture 10 of suitable size. The wall9 supports on its front side a vertically adjustable light stop 11, thelower horizontal edge 12 of which may be moved relative to the aperturelOfor increasingvertically the size of the aperture; the verticallymovable stop 11 being provided with an upwardly extending bar projectingabove the top of the box 2, and which may be secured in its adjustedposition by a screw let or other appropriate device.

Attached on the front of the wall 9 is a light stop or strip 15,designed to form the lower horizontal edge of the aperture 10 in thewall 9. In order to adjust the width of the opening 10 in the wall 9, Ihave provided horizontallyadjustable stops 16 which maybe moved towardor from each other and are mounted on suitable friction supports 17. Ifa wide or narrow opening 10 is desired, the horizontally adjustablestrips 16 are accordingly adjusted toward or from the vertical center ofthe wall 9, and if the vertical end of the aperture 10 is to beadjusted, the vertically adjustable stop 11 is correspondingly moved.

Immediately-in the'rear of the transverse vertical wall 9 of the box 2there is provided a carriage 18, formed of a rectangular frame ofchannel material; the carriage extending held by a clip 18. The verticallength of the plate-holder 20 is such that it may be I elevated bodilyto the upper portion of the carriage 18 so that the bottom edge of theplate-holder becomes approximately even with the horizontal light stop15 at the bottom of the aperture 10 in the wall 9.

Referring to Figs. 2 and 3 a clear understanding of the construction ofthe plateholder 20 may be had; this being shown in these views ascomprising a holder section,

designated at 20, into'which may be fitted a plate 21 f'suitableproportions, the lower edge of whlch may be pressed under a reslide 24.

taining flange 22 at the bottom of the plateholder 20. A spring 23 isbowed and secured to the back wall of the plate-holder 20 and is adaptedto spring against the inserted plate 21 and force this against theretaining flanges of the plate-holder 20.

Slidable over the exposable area of the plate 21, so as to effectuallycover the latter, there is provided a front or slide 2 10f suflicientlength to be inserted and guided in the sides of the plate-holder 20,and when inserted fully into the plate-holder will effectually cover theplate 21 and will be locked by a slidable catch 25, mounted on the upperedge of the plate-holder 20, this being adapted to shift beneath a ribor lip 26 formed on the outer surface of the slide 2%. The back of theplate-holder 20 is provided with a pin 27, which projects out wardlysufiiciently to engage interchangeable strips 28, with spaced andstaggered pins 28, and which is secured under a strap 29 at the top ofthe holder.

When it is desired to make exposures of a plate 21, the loadedplate-holder is inserted in its-carriage 18, this having been movedtoward the right-hand side at the rear of the camera, as shown in Fig.5. The plateholder 20 is then adjusted vertically to its uppermostposition in the carriage 18 by means of a lifter-rod 32, which isvertically movable in the box 2 and has at its lower end a hook orprong33 adapted to be turned into engagement with a slotted prong 34, Figs. 3and 5, formed on the plate holder The operator, after having inserted aplate-holder in the carriage 18, turns the lifting-rod 32 so that itsprong 33 will enter the slot of the projectionfi i, and by then liftingthe rod 32 the plate-holder will be elevated to its uppermost positionin' the carriage 18, at which time the plate-holder lock 25 can beshifted to release the lug 26 and permit the plate-holder slide 24 to belowered from in front of the plate 21, which is now disposed in thecarriage 18, toward the aperture 10 in the wall 9, through which.

actinic rays will be admitted, as desired, to the plate 21. plate-holderand adjusted it in its uppermost position at the right-hand corner ofthe camera, in the carriage 18, andunlocked the slide 24, the operatorthen places a shift bar, Fig. 8,, on carriage brackets 31 so that thelower pin 28 of a pin strip will, when lowered, rest upon an adjustablerest 30' secured to the shift bar 30. The purpose of these pins 28 istodetermine the distance which the plate-holder 20 will be lowered.

consecutively during the operation of the camera. In order to have theplate-holder fall this predetermined distance, the operator adjusts thestrip 28 upon the plateholder' and locks it in adjusted position by -tomakethe exposures.

After having inserted the meta means of, the smallbolt 35 which isexposed on the lower edge of the plate-holder.

If the operator desires to expose the plate in four vertical rows, headjusts a pin strip 18, which is transversely moved toward the left inthe camera box, passes toward the opposite side of the camera, the shiftbar '30 will shift, when engaging the wall or side of the camera, andmove the rest 30- from under the lower pin 28 and into posi- -tionbeneath the next ofi'setpin 28, which then holds the slide in a'lowei"plane. The carriage is then returned to the right making successiveexposu-resfineanwhile. the carriage approaches the" side wall the shiftbar will be shiftedasto: the carriage and again release the plate-holderto drop to another level. By the provision of a plurality of theinterchangeable strips 28 with different numbers of staggered pins 28',the plate may be divided into any number of horizontal rows of pictures.,Having adjusted upon the plate-holder a pinstrip 28 with the desirednumber of pins 'in it, the operator then adjusts the supporting bar 30upon its rests onthe carriage. He then low ers the plate-holder'2O untilthe supporting pin 28 rests on the abutment rest 30, and

then having unlocked the slide latch 25,.

lowers the plate-holder slide 24by means of the rod 32 so as to exposethe plate 21.

When it is desired to make a number of consecutive exposures of-a movingobject, the stops 16 are adjusted toward. each other so as to make thedesired width of opening at 10. Then the back 39 of the camera havingbeen adjusted in place to exclude light before the plate-holder slide 24was lowered, the operator may focus through a focus window 39' intheback and is ready to begin This is done by shifting the carriage 18 insuccessive steps horizontally and transversely across the camera box 2,

During the period of movement of the carrier 18, in which is mounted theplateholder 20, the shutter 56 swings across the aperture 10 to preventthe admission of light rays through the same to the plate 21, exposed inthe plate-holder. As the carriage 18 comes to a stop the aperture formedbetween'the radial edges of the shutter 5-6 plate holdercarrier 18isactuated. in the present embodiment, this mechanism is indicated ascomprising a hand crank 40, se-

' 18 by means of the crank the arm 58.

able axle 42 and driving a chain 43 which passes inwardly through the.side of the camera box 2 and engages and drives a pinion 44, which issecured on the shaft 8 of the shutter 56, so that, as the crank 40 isrevolved, the shaft 8 is driven and the shutter 5 rotated. Connected tothe shaft 8 is a slotted arm 45, to which may be connected at difierentdistances from the center of shaft 8 a connecting-rod 46, pivoted at 47to a lever arm 48, which oscillates on a supporting shaft 49, on whichis mounted a ratchet wheel or other gear 50. Secured on the shaft 49 isa sprocket gear 51, driving a sprocket chain 62, whereby power isconveyed ,to another sprocket wheel 53 which is mounted on a shaft 54,this also provided with a ratchet wheel 55.

The oscillating lever 48 carries a pawl 56, engageable with the ratchetwheel 50, so that when the connecting-rod 46 pulls the lever arm 48 inone direction, the pawl 56 being will engage the ratchet wheel 50 anddrivethis, with its shaft 49, and move the sprocket chain 52 and throughthis the sprocket wheel 53. On the return movement of the arm 48 thepawl 56 swings idly over the ratchet wheel 50 and effects no movement ofthe latter. The sprocket chain 52 forms the actuator whereby theplate-holder carriage 18 is shifted; the sprocket chain 52 beingprovided with a transversely projecting pin or crank 57, whichreciprocates in a slotted arm 58 rigidly secured to the lower portion ofthe carriage 18, as shown at the bottom of Fig. 1.

lVhen the crank 40-is revolved, motion is transmitted to the shaft 8,which revolves the shutter 5-6, so that during one revolution of thisthe lever arm 48 is given a righthand and left-hand oscillation, Fig. 4,and during the latter the ratchet wheel- 50 is driven, and by this theactuating chain 52 imparts a sliding movement to the carriage pin 57engaging By this construction, when a series of consecutive picturesareto be taken on one of the horizontal rows, the carriage 18 isadvanced or' shifted, and during the time-when the lever arm 48 ismaking its idle stroke and the plate'advancing carrier 18 is stationary,then the aperture between the radial edgesof the shutter 56 swingsacross the aperture 10 through which light may be admitted momentarilyto the stationary plate; the-movement of the shutter being so timed thatthe light will be out off before the next shifting movement of thecarrier 18 is begun. The width of .a picture in a horizontal row isvariable by adjusting the crank stroke of the connecting rod at theslotted arm 45.

Assuming that one is ready to make exposures on the plate 21, the crank40 is revolved and the plate-holder carriage 18 is shifted its firststep toward the left to bring a given area of the plate 21 in front ofthe aperture 10 in the wall ,9. As soon as the, plate-holder comes torest, the aperture of the stop 5-6 swings across the opening 10 and thatarea of the plate which is adjacent to the aperture is exposed. Then theshutter cuts 03 the light and the next consecu- 75 tivemovement of thecarrier 18 1s performed, this continuing successively until a series ofexposures have been made on the uppermost part of the plate, when thelowermost pin 28 will ride off of the rest 30 un- 30 til the nextprojecting pin 28 of the strip 28 engages the sliding rest 30. Thecontinued rotation of the crank 40 will shift the plate-holder andcarriage 18 to the right in successive consecutive movements. An 5exposure is made during the period between each movement of the carrier18 when the plate-holder 20 will again be dropped a predeternined'distance by the falling of a pin 28 from that shifting rest 30 onwhich it was supported.

l/Vhen the exposures are made by the mechanism driven from the crank 40,they will be of the instantaneous character and the exposures may bemade of moving or stationary objects, as desired. Should the operatordesire to make timeexposures, this can readily be accomplished byshifting the plate-holder carrier 18 by actuating the ratchet wheel 55through means of a pawl i 60, engageable with the ratchet wheel 55 andcarried on an oscillating arm 61 mounted on the shaft 54. The arm 61 isconnected to a handle 62 projecting through the side of the camera frame2 and which the operator may reciprocate when he desires to manuallyshift the carriage 18 to make time exposures. It-will be seen that bymeans of the handle 62 the lever arm 61 can be oscillated so that thepawl 60 will actuate its respective ratchet wheel 55 and thus move thecarrier actuator or chain 52, and through means of its crank or pin 57moves theslide arm 58 of the carrier 18.

In order to aid the operator, when manually shifting the carrier 18, tostop the latter at a predetermined position so as to make uniformexposures horizontally on the plate 21, I provide on the rear of thecamera, at its lowermost edge, an index plate 63 having a series ofnumerals as 22 arranged in a horizontal line, numbers 333 arranged in alower line, and numbers 44 44 still lower. The numbers 22 indicate thattwo exposures are to be made horizontally at the upper edge of the plate21, while the numbers 333 indicate that the plate is dividedhorizontally into three sections, etc.

The operator, when making the exposures shifts the carriage 18, to thelower edge of which is secured an indicating finger 64: which projectsoutwardly and over the index plate 63; the operator watching the movingfinger 64 until it registers with one of the numbers indicating thedivisions, horizontally, in which the plate will be ex posed. Thus, whenhe has to make three ex posures horizontally on a plate, thehorizontally adjustable stops 16 are adjusted to give a predeterminedwidth of aperture 10 in the wall 9; the width of this aperture beingsufiicient to make three equal exposures horizontally on the plate 21;As the operator recipro'cates the handle 62, the intermittent sidemotion of the carrier 18 can be stopped when the index pointerGregisters with the first numeral 3 on the index plate 63, whereupon theexposure may be made and the carrier 18 is then shifted again until theindicator finger 64 registers with the next number 3, and then againuntil the last number 3 is indicated.

As the carrier 18 approaches the extreme right or left-hand position inthe camera frame 2, the plate-holder is automatically lowered by reasonof the falling of the supv porting pin 28 from the supporting lug 30 asthe bar 30 is shifted. This alternately continues until the plate-holderhas been lowered to the bottom of the carrier 18.

When the operator desires to make time exposures and manipulate thecarrier 18 by hand, the shutter 5-6'will have been adjusted relative tothe aperture 10, so that the' opening between the radial edges 56 corresponds with the aperture 10 of the wall 9,

and the shutter will not be actuated when the I claim and desire tosecure by Letters Patent is 1.
